is in part very granular, resembling in this respect the Seelasgen 

 iron.* But the cleavage is in some parts very marked, and the 

 two cleavage angles measured were 120°. In breaking up the 

 iron four cleavage planes were obtained, one of the surfaces 

 being 2 cm square and two others 3 cm square each, which were 

 very smooth and bright. On etching with weak nitric acid 

 the iron turned dark and markings became visible that had 

 all the appearance of scratches due to imperfect polishing. 

 In fact they were at first mistaken for scratches and the iron 

 was twice repolished. In this respect, and in its hardness, it 

 very closely resembles the Butcher irons. f They are the 

 Neumann figures, the result of a twinning of the cube 

 described by Tschermak.;}; The iron was then treated with 

 strong nitric acid and evenly dissolved away, with the ex- 

 ception of the (see figure) eating out of one of the layers 

 parallel with the cleavage face and undoubtedly the same with 

 it. It has included round masses of troilite distributed quite 

 plentifully through it, from 3 to 8 mm in diameter, and on 

 polishing down the side of the iron these were found so much 

 altered as to be scarcely distinguished as such, rather resem- 

 bling compact limonite. Lawrencite, chloride of iron, is very 

 plentiful in this iron and collected in large drops on the surface 

 and rolled off into the tray containing the specimen. 



The following analyses were kindly furnished by Mr. J. 

 Edward Whitfield, of the U. S. Geological Survey.

The specific gravity of the largest piece received is 7-801. 

 There is a very slight trace of S and C but hardly enough to 

 determine. 



This iron does not bear the slightest resemblance to either of 

 the Whitfield County, Georgia, irons,§ and is a white iron, 

 whereas the Walker County, Alabama, iron || has a bluish cast 

 and was found over 100 miles due east. 



The writer desires to extend his thanks to Mr. Whitfield for 

 the analyses and to Prof. F. W. Clarke for his courtesy.
